A seat back pad 70 has a groove 73 for tucking a skin material therein, formed at borders between a central portion 71 and side portions 72. A hole (slot hole 74) is formed in a bottom of the groove 73 along the groove 73. A tuck-in wire 76 for tucking the skin material in includes a plurality of tuck-in portions 76A provided along the groove 73, and a connecting portion (detour portion 76B) detouring around the hole and connecting the tuck-in portions 76A. With this configuration, when an upper body of an occupant P subsides into a seat back S2 in a rear-end collision of a vehicle, the central portion 71, defined by the groove 73 as a border, is easily and sufficiently moved rearward relative to the left and right side portions 72. Furthermore, the tuck-in wire 76 is not exposed through the hole, and thus adhesion between the seat back pad 70 and the tuck-in wire 76 can be improved.

There is provided a vehicle seat (car seat) comprising a seat cushion pad (seat body) having an air passage connected to an outlet port (114), and a blower having an inlet port (113) and configured to feed air taken in through the inlet port (113) to the air passage. The blower (100) is located on the lower side of the seat cushion pad (seat body) that is opposite to an occupant's side on which an occupant is to be seated, and the inlet port (113) is directed upward that is a direction toward the seat cushion pad (seat body).

A seat for a vehicle is provided which is capable of minimizing excessive depression in a region of a sheet-shaped elastic material corresponding to an occupant's buttocks while reducing components in a seat cushion employing a sheet-shaped elastic material. The seat cushion of the vehicle seat includes: a cushion pad; a left side frame; a right side frame; a front frame disposed between a front portion of the right side frame and a front portion of the left side frame; a rear frame disposed between a rear portion of the right side frame and a rear portion of the left side frame; and a sheet-shaped elastic material disposed between the front frame and the rear frame to support the cushion pad from below. The sheet-shaped elastic material includes a rigid reinforcement portion to minimize an amount of stretch of the sheet-shaped elastic material in a front-rear direction.

The present invention relates to support apparatus for supporting at least a portion of a gluteal region of a user while the user is seated in a seating apparatus comprising a seating surface, a back support surface and a transition region at the intersection of the seating surface and the back support surface. The support apparatus a support member structured to support at least a portion of the gluteal region of the user. The support apparatus further comprises a support element structured to position the support member at the transition region of seating apparatus such that the support member extends between the seating surface and the back support surface of the seating apparatus.

Provided are methods for automatically adjusting a vehicle seating area based on the characteristics of a passenger. In an example method, a seat adjustment system of a vehicle receives sensor data representing at least one measurement of a user exterior to the vehicle, determines at least one characteristic of the based on the sensor data, determines at least one modification to a seating area of the vehicle based on the at least one characteristic of the user, and causes the seating area to be adjusted in accordance with the at least one modification. Systems and computer program products are also provided.

Disclosed are a hot melt tape for hook-and-loop fasteners without sewing which may be adhered at a low temperature and complete hardening of an adhesive resin in a short time and a method for manufacturing a seat padding material for vehicles using the same. The method includes preparing the padding material and a hook-and-loop fabric, preparing a hot melt tape having a hot melt resin layer by coating a surface of a release paper with a reactive hot melt resin having a melting point of 40-80° C. before reacting, adhering the hot melt tape to a surface of the padding material by applying heat of a temperature of 30-70° C. and pressure thereto, removing the release paper, adhering the hook-and-loop fabric to the exposed hot melt resin layer, and hardening the hot melt resin layer by cooling the padding material and the hook-and-loop fabric to a temperature of 0-20° C.

Various embodiments include illustrative vehicle seats, systems, vehicles, and methods for circulating airflow through a vehicle seat. An illustrative vehicle seat includes a cushion. The cushion is adapted to provide airflow therethrough. The cushion defines a primary airflow path directed to a primary outlet formed in a supporting portion of the cushion. The supporting portion of the cushion is adapted to receive direct body contact with a vehicle occupant while the vehicle occupant is seated within the vehicle seat. The cushion also defines a secondary airflow path directed to a secondary outlet formed in a non-supporting portion of the cushion.

A cushion component includes a lattice matrix having a first section comprised of a plurality of 3D cells. Each 3D cell of the plurality of 3D cells of the first section of the lattice matrix includes a face-centered cubic geometry. A second section of the lattice matrix is positioned below the first section and includes a plurality of 3D cells. Each 3D cell of the plurality of 3D cells of the second section of the lattice matrix includes a body-centered cubic geometry. The first section and the second section of the lattice matrix are integrated to define a monolithic structure comprised of a common material.

A headrest assembly includes a lattice matrix having a plurality of three-dimensional (3D) cells. Each 3D cell of includes a node and a plurality of links outwardly extending from the node. The lattice matrix includes a plurality of sections including a first section having a first overall elastic modulus, a second section positioned adjacent to the first section and having a second overall elastic modulus that is higher than the first overall elastic modulus of the first section, and a third section positioned adjacent to the second section and having a third overall elastic modulus that is higher than the second overall elastic modulus of the second section. The lattice matrix is integrally constructed using an additive manufacturing technique, wherein the 3D cells of each section are provided in various patterns and cured to varying degrees to provide the varying overall elastic moduli of each section of the lattice matrix.
